A supersonic aircraft flies at M{ = 2.7 at 20 km altitude on a standard day. Air enters
the engine inlet system where it is slowed isentropically to M2 = 1.3. A normal shock
occurs at that location. The resulting subsonic flow is decelerated further to M4 = 0.40.
The subsonic diffusion is adiabatic but not isentropic; the final pressure is 104 kPa
(abs). Evaluate (a) the stagnation temperature for the flow, (b) the pressure change
across the shock, (c) the entropy change, ^4 ? 5-,, and (d) the final stagnation pressure.
